Patent GB-2173744-A (GB)
Title: Sectional vessels
Inventor: BECKETT MICHAEL THOMAS
IPC: B63B3/08
Filed: 1985-04-11
Abstract: Adjustable size boats or ships comprise separate sections that are totally self floating and that will lock or join to others to form a larger vessel. A small unit which is a small vessel can be loaded or unloaded at a small port then taken under its own power, or by a powered unit to join other units at a convenient place, which may be powered by a larger power unit. All the units are then connected together to form a large ship for long voyages. Various styles of units to take different cargoes or passengers and separate power units make vessels more flexible and also, if a power unit is out of commission being refitted or repaired, the cargo units can still be used. Also if a unit is holed, it could be detached from other units and allowed to sink or be taken for repair, while other units continue on their journey. <IMAGE>

Title: Electronic body fat calculator device
Inventor: HAYES PHILIP
IPC: G06F19/00
Filed: 1985-06-06
Abstract: The device is one with which the user can interact in response to questions generated by the device, is simple to use, and allows an individual to compute his or her own body fat percentage. The device has an alphanumeric display, a keyboard for entering input data and instructions, a processor unit for carrying out calculations and providing output data, a non-volatile memory for storage of look-up tables of reference data, algorithms and questions/instructions, and a programmable memory for storing input and output data. By comparison of the user's calculated body fat and a preferred body fat value obtained from a stored look-up table the device can display both the preferred value and an indication of how much weight should be lost to reduce the level of over-fatness to a preferred level. <IMAGE>

Patent GB-2181615-A (GB)
Title: Coupling arrangements for coaxial cables
Inventor: CURTIS BRIAN WILLIAM
IPC: H03H1/00
Filed: 1985-10-15
Abstract: British Standards BS6513, Part 4, Section 3 requires isolation of subscriber equipment from a T.V. cable network at mains frequency and voltages. The coupling arrangement described provides a wideband (5-450 MHz) coupling using a transformer T between cable sections. Additional isolation at mains frequency is provided by capacitors C2, C3 in series with one transformer winding. The transformer T and isolating capacitors C2, C3 are connected in a screening enclosure 46, 48 which includes series capacitance elements C1a, C1b, that isolate the cable screens at mains frequency but allow return current to flow without significant radiation at the high end of the frequency range where leakage capacitance coupling through the transformer T is not negligible. In a modification, a ferrite bead (54, Figure 3) is mounted over one cable section, the series capacitive element being completed on the transformer side of the bead, and a further capacitive element being connected between the screen enclosure on the other side. <IMAGE>
Patent GB-2183821-A (GB)
Title: A temperature sensor
Inventor: FARRIES MARK CUNNINGHAM
IPC: G01K11/32
Filed: 1985-11-27
Abstract: Light is directed into one end of an optical fibre (6, 7) and the light scattered back from within the fibre is analysed by two separate sensing devices. One of them (11) is sensitive to light of the same wavelength as enters the fibre (Rayleigh scattered light). The outer (15) is sensitive to light of a shorter wavelength (anti-Stokes scattered light). The intensities of these two types of scattered light are compared in a ratio device (18) to give an indication of the temperature of the fibre. The arrangement is stated to permit a much faster response then the prior art method of comparing anti-Stokes scattered light with Stokes scattered light, since the Rayleigh scattered light is much larger and easier to measure. <IMAGE>

IPC: G08B5/36
Filed: 1986-05-09
Abstract: An apparatus for indicating a given condition of a plurality of positions, for example indicating whether counter positions are free, has input means (10) associated with each position (P1 to P16). Each input means (10) is operated when that position is free and storage means (30) store the signals received from the input means (10). Output means (34, 38) produce sequential output signals corresponding to the input signals in the order in which the input signals were stored in the storage means (30). A plurality of prerecorded messages, each associated with a particular position (P1 to P16), selectively operable by the output signals, indicate sequentially the condition of a plurality of positions in the order in which their input means (10) were operated. <IMAGE>

Inventor: BIRCH JOHN ROBERT
IPC: C12N9/72
Filed: 1986-06-30
Abstract: A process for the batch culture of animal cells comprises culturing the cells in nutrient medium characterised in that during the culture the medium is supplemented with a combined feed of one or more energy sources and one or more amino acids, and culturing is continued into the decline phase of the culture to provide the product(s) of the cells. The process is particularly applicable to genetically modified cells, especially hybridoma cell cultures to produce monoclonal antibodies. Preferably, the supplemental feed is fed to the culture at a slow rate over a prolonged period. Very significant enhancement of overall product yield may be obtained.

Title: Aircraft engine fan blade mounting
Inventor: SCHILLING JAN CHRISTOPHER
IPC: B64C11/06
Filed: 1989-06-01
Abstract: A pitch-changeable fan blade 40 is hinged to a blade platform 42 by a pin 46 surrounded by an anti-friction bushing 47. This allows the fan blade to pivot (when a foreign object strikes) as by phantom outline 40A without undesirable skewing of the pin 46. In another form of the invention several anti-friction elastomeric bushings are fastened to the blade clevis. The bushings also prevent "clanking" thereby decreasing blade mount damage. The description develops the occurrence of vibration or resonance in the fan blade and teaches means for damping the vibration by suitable orientation of the hinge pin. The description also teaches a blade construction containing fibres, a foam core with a metallic leading edge for protection against bird strike damage and for providing a conductive path for dissipating lightning strikes.

Title: Load current regulator

IPC: G05F1/45
Filed: 1990-06-15
Abstract: System for regulating the mean current flowing through a load (1), particularly an electric device controlling a fluid actuator drive valve receives initial variable control information ( alpha ) and a DC supply voltage. A look-up table (5, 6) provides a mean theoretical load current value corresponding to each measured value of the information ( alpha ) and means (8) computes, from the determined value of the mean theoretical current and the measured value (7) of the DC supply voltage, a theoretical value of the cyclic ratio (pwm) of a pre-determined fixed frequency square wave voltage signal to be applied to a chopper circuit (2). The real mean current (10) flowing through the load is compared (11) with the theoretical mean current to generate an error signal for correcting (9) the theoretical value of the cyclic ratio. The information ( alpha ) may be the angle of inclination of a manual controller. <IMAGE>
